Update,
So I cut open about a foot of the sensor harness on the left front and took the tape off the wire junction where the left front abs wheel sensor harness meets with a main harness just inside the left front frame rail under the top radiator hose. I did nothing else to the harness inside the frame rail except remove the tape. I did unwind the twisted pair about a foot up from where it plugs into the abs wheels sensor on the left front to inspect for any visual problems. I saw nothing alarming and let it twist back together on its' own looser then it was stock and taped it back up with electrical tape, re secured the harness to the factory clips and plugged it back into the wheel sensor. It has not done any of the low speed activating since. Go figure right. I am going to monitor this for a while and report back again. It has been fine all week with just normal test activating at the normal times as it always has. Usually after backing up and going to drive.
I was planning on data loging it to see what was going on but untill it will do it regularly again I can't do that so we shall see how long this lasts.
